GREASE-TRAP FOR SINKS.

SaPl-L'CIFICATION forming part of Letters Patent No. 323,532, dated August 4, 1885.

Application filed February 2, 1885.

To ail whom it may concern.-

Be it known that 1, JOHN REID, of Yonkers, in the county of WVestchester and State of New York, have invented an Improvement in Grease-Traps for Sinks, of which the following is a specification.

In sinks there is often considerable grease that passes off with the water into the wastepipe, and cooling, adheres to the interior of such wastepipe. Efforts have been made to detain such. grease, so as to allow of its re moval. My improvement is for simplifying the construction of the parts of the trap and for facilitating the removal of such grease. I make use of a cylinder permanently connected to the bottom of the sink, and from the lower part of this cylinder a pipe rises and passes off to the sewer. YVithin the cylinder is aremcvable grease-bucket, having an opening in one side and a slide valve or cover, and there is within the grease-bucket the inlet-tube that opens at its upper end through a removable strainer-plate. The grease accumulates within the bucket and between the same and the central inlet-tube, and when the grease is to be removed the strainer-plate and inlet-tube are raised, and in so doing the valve is closed to retain the water and grease, and the further movement lifts the grease-bucket bodily out of thestationary cylinder, so that the same can be emptied and cleansed.

In the drawings, Figure is a vertical section of the grease-trap in position for use. Fig. 2 is a similar view with the greasebueket partially lifted out, and Fig. 3 is a detached peispective view of the outlet and valve of the grease-bucket.

A represents a portion of the bottom of a sink, through which there is an opening, and the cylinder 13 is bolted firmly thereto, the joint being made water tight. The elbow G, rising-pipe I), and elbow E- are at one side of the cylinder 13, and open in through the side of such cylinder near the bottom. I prefer to make this cylinderB of east-iron, enameled on the inside, and there is a trap-screw, F, at the bottom that allows the water to be drawn off when the trap is being cleaned or scrubbed out. The sink bottom is recessed 50 for the reception of the ring 9 forming the top (No model.)

flange of the grease-bucket h, which latter is preferably of tinned copper, and within the same is a cylindrical deflector, 7c, and the inlet-pipe Z passes at its lower end within this deflector, so that water poured in the sink runs through the strainer-plate a into the pipe Z, and the deflector It gives such water an up ward direction, so that the grease rises to the top of the water in the trap and remains in the same around the inlet-pipe Z and within the bucket it. There is an opening at 0 in one side of the grease-bucket 72 through which the water runs and flows off by the pipe 0 D E to the sewer.

Upon the inside of the greasebucket it there 6 5 are slides 8, one at each side of the opening 0, and in these slides is a valve, 16: The lever r is pivoted at p and connected by the rod q to the valve, and by the rod a and joint to the under side of the strainer-plate a and pipe Z, and there is a rod, a, through the eyes 2 upon the inside of the grease-bucket and jointed at its upper end to the underside of the strainerplate a. A knob, w, with a crosspin or head at the lower end of its stem, is used to lift the 75 strainer-plate, and with it to raise the rods 'u and o. The-rod it moves the lever r and forces down the valve t and closes the opening 0 sufficiently tight to retain the water and grease in the bucket h, and on further lifting the knob 8c 20 and strainer-plate n and tube Z the rods a 1) lift the grease-bucket out bodily, and the grease can be poured off, or the entire contents discharged into a vessel, and the grease allowed to float and be separated. By this construction the grease is detained so that it does not pass off into the sewer, and it is taken out from time to time, and all portions of the trap can be easily washed out and thoroughly cleansed. W'hen returned to place, the valve t is opened by the action of rod a and lever r.

The strainer-plate and inlet tube maybe separately removable, and the valve t be closed by hand, if desired, before lifting out the grease-bucket h.

I claim as my invention- 1. The combination, with the sink, the cylinder B, and the rising discharge-pipe C D E, of the movable inlet-tube Z, and strainer a connected therewith, the grease-bucket it, having 100 an opening, 0, at one side and a slide-valve, t; to close such opening, the lifting-rods u o, the lever r and connections between the rods and the movable strainer, substantially as set forth.

2. The combination, with the cylinder 13 and rising discharge pipe, of a removable grease-bucket h, having an opening in one side thereof, a slide-valve to close the opening, the

removable inlet-tube Z, and strainer n, substantially as set forth. IO
